By default on Redhat, the output from pstree is scrambled like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 |

There are a couple of ways to clear this up so that it looks like this:

Here are two possible solutions:
1. Use “pstree -G” to force VT100 line drawing
2. Do “export LANG=’en_US'” to change the language from UTF-8 to English
One Response
To make it permanent, an alias like
alias pstree=”pstree -G”
can be added to the global bashrc file (i.e. /etc/bash.bashrc)
